When Ecology learns about a release of a hazardous substance into the environment, we do an Initial Investigation. Release information may come to us through the Environmental Report Tracking System (ERTS), either from the property owner making a required notification or as a complaint from someone who saw the release.

During the Initial Investigation, we evaluate environmental conditions at the property and review all available data. The goal of the Investigation is to determine if the release may pose a threat to human health or the environment, and if further cleanup actions are needed.  We track any site that is suspected or confirmed to be contaminated with hazardous materials, as required by the Model Toxics Control Act (MTCA).

Ecology has conducted an Initial Investigation and determined that remedial action is needed at this site. Ecology will establish a priority for further investigation and cleanup of this sediment site under the formal MTCA cleanup process.
